IMPROVEMENT HYDRANTS.

The Schedule referred to in these Letters Patent and pan or the same.

To all whom it may concern:

Be it known that I, HARRY J. BAILEY, of Pittsburg, in the county of Allegheny, and State of Pennsylva-v nia, have inventeda new and useful Improvement in Hydrants; and I do hereby' declare the following to be a full, clear, and exact deseption thereof,'reier ence being' had to the accompanying drawing', making a part of this specification, in which- Figure 1l is a-vertical section, formed b v a plane passing through' the axial line ot the outlet-pipe,

Figure 2 is a perspective view of' the inner removable parts of thehydrant; and

Figure 3 is an upper face view of the devices shown in fig. l2, and o f the case in which they work.

Like letters of reference indicate like parts in each. The nature of my invention consists in such con struction of a hydrant-valve packing and fastening as that- First, the lower face ofthe valve shall-close thesupl'` C is a valve-box or case, ot' tubular form, and with i differently-sized recesses, as present-ly to be described.

O11 the lower end of the outlet-pipe B is a hollow double-seated-valve, a, with perforations a', in its sides.

Its lower faee'is packed with a gasket, s, so as to fit neatly on-a valve-seat in the upper open end of the supply-pipe A- Its upper edge projects out laterally beyond the 'pipe B, on to which it is screwed sutiicien-tly far to give a seat, which, when the valve" is raised, comes against the lower face of the annular packing-ring b.

The lower cavity or recess c is rimmed out to receive the valve a, but is so made'as to leave -rooni between the two, when th valve a, is raised, for the upward flow ot'- the water from' the supply-pipe A, through the perforations c', whence it passes upward through the outlet-pipe B'.

The cavity above is recessed out for the annular packing-ring b, the lower endl of the packing-ring resting on the step or shoulder b', where it is held tirinly by the inclined screw-plate d, through ,which the pipe B passes. t

ln the edges of the inclined plate el are notches c, by which theinclined plate .isfslipped down into the cavity f o f the box O, below the projections e.

The upper face of the plate d made with inclined tti-ces d', like the faces of a crab, or clutch, such as used in machinery to prevent motion in one direction while permitting it in the opposite direct-ion.

Above this plate d, and rigidly attached tothe pipe B, is a collar or nut, y, onthe opposite sides of which are lugs g', andthese in tuin engage similarlyfshaped lugs hr, on the upper face 'o i the plate d.

Theil, by using the pipe B as ascrew-dliver, the

lugs g are made to engage the lugs h.

The inclined faces df'then acting under the projectioi'is. c/ on the screw-principle, the plate l is forced down, so as to hold the valve in place," and prevent it receiving other motion than that neuessaryto open and close it.

To take thevalve out, it is only necessary to reverse :the motion, unscrew the plate d till the notches c correspond with t'he proj eet-ions e, when the valve a, packingiin'g b, plate d, with the outlet-pipe B,1'nav beremoved.

.The j iacking-ring b iitting closely around the pipe B, and also resting snugly in its -recess or cavity, closes all connection between the supply and outlet-pipes,

"except through the valve c, and through the waste,

which consists oi' a groove, i, extending along the outer face of the pipe B, from at or near its junction with the upper seat ofthe valve a, upward till it opens above the packing-ring'lj into the outletpipe B, o r into the box C, or both.'

The parts thus described are soV made, relatively to each other, that-the outlet-pipe B, carrying, as `it does, on its lower end, the valve (t, may have a slight vertical motion or lift, sutlieient to-raise the latter yfrom its seat on the open end lof the pipe A. The water then .flows upward between the valve a. and the sides of its recess a, through the peribrations a', and out bythe pipe B. At the same time, the raising of the 'pipe B inside the packing-'ring b, brings the lower Aend of the waste-groove i above the lower edge of the ring,T b, whereby it is covered, and the waste is cut oii By depressing the pipe. B, `the valve c is lowered to its seat, andthe lower end of the waste "i, coming belowthe ring 11.is uncovered, and the water above the valve is allowed to escape.

Fig. 1 shows the position fof the devices when the valve is open for the outflow of water.

-The packing-ring b, it .will be observed, is rigidly iixed, encircling theoutlet-pipe, covering the Waste,

and through which the outlet-pipe works up and down,

to open und close the waste.

The plate 1l holds the packing1i11g toits place, and thereby prevents the valve from being,I lifted too far from its seat, or moving in any' otherthan the proper vertical direction.

. It' the aste-groove i extends ydown to thel upper face ofthe valve a, it is then closed, when the valve u is' raised by .suoli upper face coming against th(` lower thee ofthe packing-ring l). The valve c in such rase 'peribrnis a double function: it closes the supply-pipe when down, and the waste when up, and cicc versa.

Another advantage, and a very material one, is this,

that ythe waste-groove ibeing in the outlet-pipe A, can

be removed with it, to be cleaned, when, as it sometimes'does, it becomes fouled or clogged. '.Lhe whole valve, in fact, and all fixtures connevted therewith, may he lifted out, to be cleaned, repaired, or renewed.

What claim as my invention, and desireto secure by Letters Patent, is-

f. A double-'faced valve u, so mal-deas to close down onvthe supply-pipo, to cut oil' the ow of water, and upward against the stationary packiug-ring b, to close the waste, substantia'blly as hereinlwjbre setforth.

2. The waste-groove i of a hydm-nt, in the outer face. of the outlet-pipe, so armnged, relatively-tothe annular stationary pzckingfring b :unl valve a, as to be opened andclsed" by the 'closing and opening of the valve, and so as to be removable, suhsfanially as and for the. purposes hereinbelhre expressed.

3. The outlet-pipe B, working vertieall)- through the stationary packntg-rng b, to open and close the valve, substantially as and'for the purposes hereinhetore set fort-l1.

In testimony whereof, I, the said' HARK-Y1 BAILEY, have hereunto set my hand..
